This products adds this html code to every page of your forum
I did not see where product author mentioned this in his product description.

Try reading the first couple of pages of this topic ;)

You are right. But this need to be either mentioned in product description, or this product should be deleted on vbulletin.org

A copyright notice in the footer is common practise and not a reason to delete a modification from vB.org (providing it is not linking to Warez/Adult content, etc..).

It is the users choice to accept this and install the modification or not.

(PS I do agree with mot of those that complain that a copyright notice should only be placed on pages where the modification is active, but this is the authors choice)

I agree that a copyright notice is okay. But I need to know that there is a notice and where it is placed. Here it is placed on *all* of my pages. This for an administorial modification! You'd never think there's a copyright notice at all. If administrators just install this mod, they do not always look around what this modification displays on places which have nothing to do with this mod.

I never installed a mod and then searched my website for additional copyright notices (which is here also linked - bad for SEO). And I installed a lot of mods. But now I do. Does not make vb.org a more secure place for me.

Yes. it could be easier. I'll find out whether it has any limitation or not.

It seems like your host has a kind of firewall. contact your host regarding this.

I'll give this a good test :)

after install - email notifications for users is no longer working - any ideas ?

This isn't good to be implemented. because the message-ID will be quoted in the body of the bounce message. the existence of it isn't guaranteed.

On the other hand, scanning the header of the bounce message is enough to retrieve the special email address.

Uninstall. reinstall.
